GB/T 46456 "Interconnection of Information Technology Devices and Interoperability of Smart Homes" specifies the architecture and general requirements for interoperability of smart homes. This document covers topics such as data classification and description, testing and evaluation methods, aiming to provide a framework for information equipment between different brands and between different product categories within the same brand. This will provide a basis and guidance for the interconnection and interoperability of home products such as communication equipment, household and similar appliances, audio and video equipment, and security equipment. It consists of seven parts.

1.Architecture and General Requirements. The aim is to provide the architecture for smart home interconnectivity, as well as the implementation devices and control systems. The general requirements for interconnection and interoperability of equipment, gateways, service platforms, etc.

2.Test Methodology. The aim is to provide execution devices, control devices, gateways, and service platforms that conform to the requirements of Part 1. Methods for testing and verifying interoperability functions.

3.General Requirements for Local Area Networking. The purpose is to provide the functional requirements and message parameter requirements for implementing local area network interconnection.

4.Local Area Network (LAN) Interconnection Testing Methods. The purpose is to provide testing and verification methods for LANs that meet the requirements of Part 3.

5.Classification and Description of Sensing Data. The aim is to provide data for classifying and describing the home environment and family needs to support smart home interconnectivity. Classification and description methods of smart home sensing data, including user data and data on non-device items.

6.System Intelligence Hierarchy. The aim is to provide principles for the intelligence hierarchy of interconnected smart home systems. And the basis.

7.General Requirements for Scenarios. The purpose is to provide the components, classifications, and descriptions of scenarios that support smart home interconnectivity. Requirements, etc. Interconnection of information technology devices and smart home interconnection Part

1 Scope

GB/T 46456.3-2025 is the Chinese national standard covering smart home devices talking to each other on the local network without going through a cloud - the discovery and pairing, the message format and the device model, the security of the local link, and the behaviour when the internet is down. Part 3 of the series, first edition. In force from 1 February 2026. Issued on 5 October 2025, it has been in force since 1 February 2026.

This document specifies the device discovery, device connection, device collaboration, device subscription, device notification, and device control for smart home local area interconnection. Functional requirements and corresponding message parameter requirements. This document applies to the design, research and development, and production of smart home interconnection systems in a local area network environment.
